IMPROVEMENT IN SEED-DRlL LS.

Specification forming part of Letters Patent No. 26,612, dated December 27, 1859.

To all whom it may concern:

Be it known that I, WORDEN P. PENN, of Belleville, in the county of St. Clair and State of Illinois, have invented a new and useful Improvement in Seed-Drills; and Ido hereby declare that the following is afull, clear, and exact description of the same, reference being bad to the annexed drawings, making part of this spccificalion, in which Figure l is a plan; Fig. 2, a side elevation, and Fig.3 a transverse section through A A.

To enable others skilled in the arts to which my invention appertains to make and use the same, I will proceed to describe the construction and operation thereo Similar letters of reference represent corre sponding parts of the different figures of the drawings annexed.

Upon the drawings. A represents the frame of the machine, and G the truck-wheels, the axles of which are bolted to the frame of the machine. Across the frame a hopper-box, D, is fixed in the manner shown, and in the bottom of the said box a series of angular holes are cut, as shown at ac, Fig. 2, into which a series of angular wheels, E, are made to work, which are fixed upon the shaft'E in the bottom of the box aforesaid. This shaft E receives a rotating motion through the agency of a cog-wheel, J, fixed upon one of its ends, and which meshes into a corresponding wheel, Ll, fixed to the hub of the wheel 0, from whence it receives its motion. To the under side of the hopper-box a bracket, 11, is fixed, or

which valves r are fixed (equal in number to the holes in the bottom of the box) and so arranged as to work over the valves and under the bottom of the box D. To the bar tchains fare fixed, which are also attached to the bar T, and which passes around the two frame-pieces A" A in the manner shown, and to the bar T' there are also a number of chains,f, one for each of the hoes or flukes Q, to which the said chains are also attached in the manner shown. Now, the bar T, being fixed upon centers P in the frame, so as to have an eccentric momunication with the leader h, which receives t the seed from the hopper-box, from whence it falls to the ground through the tubes ligand 1 flukes Q, these latter being supported by the drag-bars or braces F in the ordinary manner. Thus much for the construction.

The operation is as follows: The seed, being first put into the hopper-box, is fed by the r wheels E through the holes or, from whence it is conveyed to the ground through the agency of the leader h, tube R, and fluke Q. The flow of seed through the hopper is regulated by the valve 8, which may be so adjusted as to allow more or less seed to pass through, as the case may require, the said valve being securedat any given position by means ot'a pin, which is passed through the bracket K (fixed against f one end of the hopper) into the end ofthe valve,

which is made to project beyond one end of the hopper. as shown at Fig. 1 at s. The fiow of grain through the machine is stopped by the valves r whenever the flukes are raised from the ground, as the same power and motion which raises the flukes cfi' of the ground also closes the valves by means of the arrangement of chains with the valve-bar t, eccentric bar T and the valves with the hopper-box, all being combined as described, so as to cheat the object sought after-viz, shut off the flow of seed at the same time the flukes are raised off of the ground-with the described arranget ment and combination of valves.

I alfl aware that the valves of the hopperbox have been closed simultaneously with the raising of the flukes olfot the ground. This, therelore, I do not claim as such, but

What I claim is- The arrangement of endless chain fwith the eccentric bar T and valve-bar t, with the valves w theretoattached, for the purpose of closing and opening the said valves and. raising the flukes simultaneously,in the manner described.
